Clarify Login Label (Email Address)

Description

r36620 changed the login label from Username to Username or Email once logging in via email address was added.

I'd like to see that clarified further, as Username or Email Address. It's simply clearer and more accurate language (in English variants at least). Those who are mostly unfamiliar with logging-in in general, or have cognitive difficulties, will appreciate being told it's the address we're after, and not an actual email that should be pasted in.

I'd disagree (of course). They are different things. I can give you my "email address" (me@example.com), but I can't give you my "email" unless I forward the whole of my inbox to you. Likewise, my home (the building), and my home address (what you'd write on an envelope) are different things. If you want to send me a Christmas card, I'm not going to give you my home.

A similar comparison would be how some people use the term "blog" as a shortened version of "blog post". As web-savvy users, we could probably guess that those people mean a single post, instead of the collection of posts, but what they are saying isn't technically correct.

The point here is to be accurate with language, and avoid the use of colloquialisms, especially on the front-end for something as critical as logging in.

If so, this should likely be changed across the board, for example on the "Add New User" screen(s).

I did see that, but wanted this ticket to have a narrow scope. I'm all for updating Add New User screen too.
